I want to install a utility sink in my basement. The problem is that the main sewer line is on the other side of the house and there is no way to run a pipe from where I want the sink to the main sewer line easily and without running through a finished portion of the basement. There is however an auxiliary vent pipe right next to where I want the utility sink (see pic). This vent pipe vents fixtures in the second level of my house and directly vents through the roof. Here's my question. Is it okay and to code if I drained the utility sink directly into the auxiliary vent? Is this considered wet venting? Would you expect there to be any problems with this set up? Any insight would be greatly appreciated here. Thanks!
What's above this pipe? My guess is that it's a drain to a sink or something upstairs and likely not just a vent.
If it is just a vent, yes, you can use it as a drain without a problem.
If there is a sink/fixture above, you technically can not use it as a drain... but though it's not code compliant, I don't see a huge issue with it. It's technically a wet vent, but in your situation, I think it's better than a separate laundry pump, etc.
Anyway, I would cut off the threaded plug adapter, and extend out from that tee - or replace the whole tee using a no-hub coupler if you need it pointing the other direction. Add a trap adapter and a 1.5" slip trap into your laundry tub and you'll be all set!
Got it. Thank you for the reply! I've ran every sink/fixture in my house and nothing drains in that line. It definitely goes upstairs and then through the roof so I was guessing this is a vent line only for the upstairs fixtures.
That pipe is a drain for something. Vent lines do not extend below the fixtures they protect. Are there rough-in's in your basement for a future bathroom?
Thank you for the reply. There are no rough-in's in my basement for a future bathroom and I can't seem to find anything that drains into that line. Any advice? I would like to be complaint with code if possible but I really want to make sure draining into this line will not cause any problem and it sounds like it won't from the Zorfdt's reply.
Scenario
I have an indoor flow problem and I suspect the water softener but I am not sure. Anytime 2 fixtures are on I have a noticeable drop in the water pressure. I am looking for tips that would prevent me from tearing parts of my plumbing out.
The house is a 2018 build with all PEX plumbing, every fixture is fed by a dedicated 1/2 line and no 2 fixtures share a 1/2 line they all meet a 3/4. PEX is PEX A with expandable fittings. I have an AO Smith 35000 water softener. I installed the Softener myself and used PEX B with insert fittings there are about 5 3/4 bends with insert fittings. Well is a 3/4 hp I am unsure of the well depth but it is set to 40/60psi. Well incoming has immediate a 3/4 inch T off to to outside spigot and house. Well pump can build pressure fast, I can't open enough fixtures in the house or outside to where the pump can't keep up an cycle off.
What I have tested.
If I run anything outside with both spigot's with multiple hoses for example to water lawn I don't see this pressure drop in the house. This tells me it is not something with the well pump or pressure tank. When I set the Water Softener to Bypass I still see the same exact pressure drop. The pressure drop doesn't seem any different when the well is close to it's 60psi shut off vs 40 when it kicks on. I don't get why I see the same pressure drop with the softener bypassed. The Softeners specs only indicate a service flow rate of 7.5gpm @15psi which seems useless to me because I don't know what the service flow at 40-60psi is.
My Questions
The the softener so restrictive that even in Bypass it still restricts? I should install an actual 3/4 inch bypass before the softener with the proper shut offs to test? Could it be the 5 insert style PEX fittings? Could it be something else? I would suspect the PEX fittings or softener would be a restriction if I opened 4 or 5 fixtures but not 2. Oh and if I run 4 things at once my water turns to a trickle.
Hello question on which pipe tap I should order off of the bay. I'm tapping a steel water well drill bit with a 1" NPT steel pipe (the one from home depot) schedule 40. I ordered this tap from ebay[h3]1 in. -11-1/2 carbon steel npt pipe tap | drill america series qualtech dwtpt[/h3][h4]It is too small.
